Abstract: Patients who fulfilled the inclusion criteria were randomized into three distinct groups: an outpatient group who performed all activities at the clinic, a home-based group who performed the activities at home and a control group. PR consisted of a combination of aerobic exercises and strengthening of upper and lower limbs 3 times a week for 12 weeks.There was a significant difference in the distance covered on the six-minute walk test (p < 0.05) and BODE index (p < 0.001) in the outpatient and at-home groups after participating in the rehabilitation program compared to baseline.A home-based self-monitoring pulmonary rehabilitation program is as effective as outpatient pulmonary rehabilitation and is a valid alternative for the management of patients with COPD.Chronic obstructive pulmonary disease (COPD) is a common cause of illness and death that affects a large and increasing number of individuals in both developed and developing countries. Estimates suggest that COPD will become the 3rd most common cause of death in the world and 5th most common cause of illness in the next 20 years [1,2].Pulmonary rehabilitation (PR) is a multidisciplinary intervention that integrates physical exercise, nutritional therapy, patient education and psychological support [3-7]. Evidence indicates that PR offers numerous clinical benefits, such as improved health-related quality of life, a reduction in anxiety and depression, increased tolerance to physical exercise and a reduction in the number of hospitalizations and days of hospital stay per year [3,4]. However, despite the strong scientific recommendations for its routine use in the treatment of COPD, PR is generally underutilized [5-7]. A survey carried out in 2005 in Canada demonstrated that only 1-2% of the Canadian population with COPD has access to rehabilitation programs [8]. Similar statistics are reported for other countries [7,9].A search of the scientific literature revealed few controlled studies that demonstrate the b
Novo-desenvolvimento, capital social e desigualdade social

Abstract: Este artigo aborda a tendência de enfrentamento da desigualdade social a partir, no campo econ mico, da vers o do novo-desenvolvimentismo e, no campo político e ideológico, a partir da no o de capital social, na tentativa de realizar um "capitalismo com face mais humana". Discutiremos duas ordens de quest es, considerando a especificidade da forma o social brasileira de capitalismo dependente: 1) a “constru o de Estados fortes” para assegurar as condi es de acumula o do capital, ampliando as margens do mercado de consumo, aliviando a pobreza e controlando possíveis tens es políticas e 2) a difus o da necessidade de construir uma sociedade em harmonia, que se traduz na incorpora o da ética empreendedora dos empresários em todas as esferas sociais. Entendemos que este escopo político-econ mico revela uma nova pedagogia da hegemonia, sustentada numa suposta alternativa de gerenciamento das novas express es da “quest o social”, voltada para educar o conformismo e ocultar o conflito de classes.

Abstract: in order to adjust a rain-flow model capable of estimating santa barbara river minimum flows, the authors analyzed the historical flow series and identified the base flow recession phase. the daily rainfall data observed at the stations fazenda alian?a, joviania, ponte sul goiana, maurilandia and ponte meia ponte were used to determine the total rainfall during the five months preceeding the dry season (p5). the average p5 for santa barbara river basin was obtained using the thiessen method. the rain-flow model produced in this work presented little errors compared with the minimum flows actually observed in the river during the dry season. the model allowed the authors to estimate the referrence flow q7,10. the method studied in this work made it possible to simulate the hidrogram corresponding to the base flow recession phase starting from p5 rainfall. this allows the public water manager in goias to prevent possible conflicts over water in the river basin using different rainfall distribution scenarios.
